Solution Overview
Problem
Conventional shoes often fail to provide a precise fit and optimal support for individual foot shapes and walking styles, particularly in medical-orthopaedic and sports applications, where specific demands and stresses require tailored footwear solutions.
Innovation Solution
A shoe sole designed according to individual biometric data, combining three-dimensional foot shape, weight distribution, and walking patterns, manufactured using rapid prototyping processes like laser sintering to create a one-piece insole and outsole with customizable features such as flexible areas, heel height, and stud configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional mass-production methods are used for shoes, then manufacturing efficiency and cost-effectiveness are improved, but the fit and comfort for individual wearers deteriorate
Solution Approach 1:
The patent applies parameter changes by using biometric data to determine specific geometric parameters of the shoe sole, including the position and orientation of compliant and rigid areas, footbed profiling, heel height, and lug configuration. These parameters are customized for each wearer based on their individual foot shape, weight distribution, and walking style, resolving the contradiction between mass-production efficiency and individual fit comfort.
2Ease of operation
If custom-made shoes are crafted individually, then the fit and comfort for specific wearers are improved, but manufacturing complexity and time consumption increase
Solution Approach 1:
The patent applies preliminary action by capturing biometric data and determining all sole parameters before production begins. The complete design data for the sole and upper are created in advance based on the wearer's foot shape, weight distribution, and walking style, allowing the actual manufacturing to proceed efficiently without complex adjustments during production.
Solution Approach 2:
The patent determines multiple geometric parameters of the shoe sole based on biometric data, including the position and orientation of compliant and rigid areas, footbed profiling, heel height, and lug configuration. This systematic parameter determination approach simplifies the manufacturing process by providing complete design specifications before production.
3Ease of manufacture
If standard shoe designs are used, then manufacturing simplicity is maintained, but adaptability to individual biomechanical needs deteriorates
Solution Approach 1:
The patent applies parameter changes by determining specific geometric parameters of the shoe sole based on biometric data, including the position and orientation of compliant and rigid areas, footbed profiling, heel height, and lug configuration. This allows standard manufacturing processes to produce customized shoes that adapt to individual biomechanical needs.
Solution Approach 2:
The patent applies preliminary action by capturing biometric data and determining all sole parameters before production begins. The complete design data are created in advance based on the wearer's foot shape, weight distribution, and walking style, allowing efficient manufacturing without complex adjustments.
4Manufacturing precision
If rapid prototyping processes are used for shoe sole production, then customization capability and manufacturing precision are improved, but production time and cost for small batches increase
Solution Approach 1:
The patent applies preliminary action by capturing biometric data and determining all sole parameters before production begins. The complete design data for the sole and upper are created in advance based on the wearer's foot shape, weight distribution, and walking style, allowing rapid prototyping to proceed efficiently with pre-defined specifications.
Solution Approach 2:
The patent determines multiple geometric parameters of the shoe sole based on biometric data, including the position and orientation of compliant and rigid areas, footbed profiling, heel height, and lug configuration. This systematic parameter determination enables precise customization while maintaining production efficiency through automated data processing.
